HULLLFOR MARINE vEssELs.

SPECIFICATION forming part of Letters Patent N o. 634,814, dated Cctober 10, 1899. Application filed September Z7, 1898- Serial No. 691,984. (No model.)

To all whom t may concern/ Be it known that I, JOHN WILLIAM GLA- HOLM, a citizen of the Dominion of Canada, residing at the city of Nanaimo, in Vthe Province of British Columbia, Canada, have invented a new and useful Improvement in Hulls for Marine Vessels, (for which I have obtained a patent in Canada, No. 60,648, bearing date July 19, 1898,) of which the following is a specification.

My invention relates to improvements in the form of hulls for marine vessels of alight draft; and it has for its prime object to provide a vessel that may be adequately driven at a'high rate of speed owing to the peculiar and novel construction of the hull.l

The essential features of my invention are to have the displacement in three parts or hulls and the same converging into one bow, and also to have the ribs supporting such hull extending clear over the deck, which is preferably of convex form. I attain these objects by the mechanism illustrated in the accompanying drawings, in which-.

Figure 1 is a side elevation of my hull, showing the upper part sectioned at line 2 2 in Fig. 3. Fig. 2 is a perspective view of the stern of my hull. Fig. 3 is a vertical section of the same, taken at line 1 1 in Fig. 1; and Fig. 4 shows afview of the bow of my vessel, taken from beneath to show the three hulls connected into one bow.

Similar letters and numerals refer to similar parts throughout the several views.

In the said drawings, 10 indicates the-ribs of the vessel. These are carried over and support the main upper deck or shell B and pass around beneath, following the inner contours of the trinal hull A until the two ends meet, and the plates 11 are riveted or otherwise fastened to these ribs. To strengthen them and stiien the main upper shell or deck, stanchions 12 are placed vertically and conneet between thehulls of the vessel and the for passengers between decks.

The cabins are preferably arranged fore and aft, as indicated by the letter C, the companion-way D leading thereto from the upper deck. Tliebetween-decks are lighted from the ports E, which are glass-covered.

To further strengthen and bind the hulls together, the intervening spaces between are reinforced by gussets 15, which may be bolted through from the inner sides of the hulls. These hulls, which are built on fine lines and which are distinct and complete, present outer convex surfaces, similar to the'hull of an ordinary vessel, and they gradually converge into one bow, as shown in Fig. 4.

As shown by dotted lines intervening between the hulls, there may be arranged paddles which are arranged in paddle-boxes, and, as shown in Fig. 2, three propellers maybe conveniently employed.

From the foregoing it is evident that great` aggregate power may be adopted in the'propulsion of vessels having my improved hull, and 4it isfurther shown that my hull will be very steady owing to the broad beam-surface it occupies.

With the foregoing advantages in view it is evident that this invention may be advantageously employed in the construction of torpedo-boats.

I have in most respects specifically described the particular construction of my hull. This, however, may be modified to become adapted to the use for which the vessel is intended to be employed without departing from the form'of hull that I have described and illustrated, the form being the essential feature of my invention.

Having now described my invention, what I claim as novel, and desire to be protected in by Letters Patent, is

A vessel comprising a hull formed of three distinct portions joined to Yform a trinal hull, the three sections extending parallelly rearward and each section terminating in a distinct stern portion, the outer-hull sections. forming the sides of the vessel and merging at their front ends with the central hull, said central hull' being extended beyond the said portions to form thebow, and an arched deck having its sides merging with the outer sides of the outer-hull section, all being arranged substantially as described.
